your password input field password have name , can password value name. example
<input type="password" value="" name="pass"> your can value form backend calling
string pass = request.getparameter("pass"); anyways parameter value, should submit (post) form specific url. can include id form
<form action="login.jsp" method="post" id="myform"> and script should
<script> function callfun() { $("#myform").submit(); } </script> and let me know, if works. thanks.
